Rudall Exploration Results
High grade gold mineralisation intersected at depth
THIS ANNOUNCEMENT CONTAINS INSIDE INFORMATION AS STIPULATED UNDER THE UK
MARKET ABUSE REGULATIONS. ON PUBLICATION OF THIS ANNOUNCEMENT VIA A
REGULATORY INFORMATION SERVICE, THIS INFORMATION IS CONSIDERED TO BE IN THE
PUBLIC DOMAIN.
Greatland Gold plc (AIM:GGP; Greatland or Company) is pleased to announce the
results of its 2022 drilling programme at the 100%-owned Rudall project in the
Paterson Province of Western Australia. The Ramses target is located within
the Rudall tenement, 20km southeast of Greatland's flagship Havieron
gold-copper project. The single drill hole testing the Ramses target was
supported by a Western Australian Exploration Incentive Scheme (EIS) grant
(see RNS Announcement titled "Greatland awarded a drilling grant for Paterson
province exploration project" dated 10 May 2022).
Highlights
§ Hole RAD002 intersected 18.25m @ 22.0g/t Au from 924m (uncut) to end of
hole (EOH) at 942.25m, including 1m @ 393g/t Au from 926m. Significantly,
anomalous copper, silver, bismuth and arsenic assays were recorded within the
broad, altered intersection
§ The hole ended due to drilling limitations and mineralisation is open at
depth
§ Structural and geochemical work and a future downhole electromagnetic
survey are required to refine the potential for mineralisation to extend into
shallower positions within the system
Greatland Managing Director, Shaun Day, commented:
"Our recent drilling at Rudall has delivered a significant and high-grade
result."
"While recognising the high-grade intercept is at depth, the strong gold
mineralisation and supporting pathfinder geochemistry in consistently altered
and veined basement sediments continues to highlight the outstanding
prospectivity within Greatland's tenement package and the Paterson Province in
general."
"These results, together with our continual improvement in understanding of
the covered basement geology, stratigraphy and structure, increase our
confidence in the prospectivity of the region, and our ability to vector
towards intrusion related and other styles of mineralised systems on our
extensive ground holdings."
Overview of the 2022 Rudall Programme
The Ramses target, within the Rudall project (Figure 1), was identified as a
potential Havieron-style body from interpretation and re-modelling of regional
airborne magnetic and gravity data. Following the granting of EIS funding for
drill testing, a small, ground moving loop electromagnetic survey utilising an
Abitibi-RMIT (ARMIT) sensor probe was completed prior to drilling in an
attempt to detect a conductive body. Results were inconclusive due to the
thickness of cover. To further refine the drill target, the magnetic anomaly
was forward modelled by Adelaide Mining Geophysics (Figure 3). Modelling
estimated cover to extend to a depth of between 300m and 700m over a 500m wide
vertical roughly cylindrical body.
Diamond drill hole RAD002 was drilled to a depth of 942.25m to ensure success
in penetrating through the cover into the Proterozoic basement and magnetic
target zone.

Ramses Target
Drilling intersected the Permian Canning Basin sediment contact unconformity
at a depth of 566m downhole (approximately 557m vertical). The underlying
target Proterozoic Yeneena sedimentary stratigraphy consisted of generally
sub-horizontally bedded, fine-grained sandstones interbedded with variably
calcareous, silty sandstone to limestone rich sedimentary units.
A second, angular unconformity was noted within basement rocks at 924m
downhole, where barren, sub-horizontally bedded, dark, fine-grained
carbonaceous shaley siltstones overlay the pale green-brown,
silica-carbonate-sericite altered and mineralised sandstone package (Figures 3
and 4). Bedding in the mineralised unit below 924m displays open folding
with a maximum dip of 67(o) about an E-W fold axis, with a sub-vertical axial
planar foliation. Two cross-cutting vein sets, the first dipping 21(o)
towards the south and a steep set dipping ~70(o) towards 240(o) (SSW) were
noted in the altered sandstones which appear linked to the gold mineralisation
and alteration. The presence of iron oxide-stained sediments at such great
depth indicates potential uplift and exposure to air and water at some earlier
stage.

The entire sandstone sequence below the interpreted unconformity was altered
and mineralised, (Figure 4 and Table 2), including several narrow intervals of
significantly anomalous multi-element pathfinder elements such as bismuth,
arsenic, silver and copper (Appendix 1).
Subsequent laboratory screen fire assay check analyses for gold confirmed the
single metre, high-grade assay and overall mineralised intersection tenor.
No bias between the fine fraction and coarse fraction assays in the screen
fire results was noted, giving a high degree of confidence in the initial
results.

Next Steps
The presence of steep dipping veining within the mineralised zone increases
the potential that the mineralisation extends to the top of the basement at
approximately ~550m below surface. For context, the Havieron deposit occurs at
~420m below surface.
To test this, further structural and geochemical work along with a downhole
electromagnetic survey of hole RAD002 to identify any off-hole conductors,
will refine the potential for the mineralisation to extend to a shallower
position within the basement.

About Greatland
Greatland is a mining development and exploration company focused primarily on
precious and base metals.
The Company's flagship asset is the world-class Havieron gold-copper project
in the Paterson Province of Western Australia, discovered by Greatland and
presently under development in joint venture with ASX gold major, Newcrest
Mining Limited.
Havieron is located approximately 45km east of Newcrest's existing Telfer gold
mine. The box cut and decline to the Havieron orebody commenced in February
2021. Development continues to accelerate with record advancement achieved
in the December 2022 quarter. Havieron is intended to leverage the existing
Telfer infrastructure and processing plant. Access to Telfer will de-risk the
development, reduces capital expenditure and lowers the project's carbon
footprint.
Greatland has a proven track record of discovery and exploration success and
is pursuing the next generation of tier-one mineral deposits by applying
advanced exploration techniques in under-explored regions. Greatland has a
number of exploration projects across Western Australia and in parallel to the
development of Havieron is focused on becoming a multi-commodity miner of
significant scale.

§ Where anomalous results are quoted (Table 2) the samples have been selected
§ Where aggregate intercepts incorporate short lengths of high grade results as follows:
and longer lengths of low grade results, the procedure used for such
aggregation should be stated and some typical examples of such aggregations - Au >0.1ppm; or
should be shown in detail
- Ag >2ppm; or
§ The assumptions used for any reporting of metal equivalent values should be
clearly stated - Cu >500ppm; or
- Bi >1ppm; or
- Pb >200ppm; or
- Zn >1000ppm
- with a maximum consecutive internal waste of 3m
§ individual assays and their interval widths for reported anomalous
intervals are displayed in appendix 1
Relationship between mineralisation widths and intercept lengths § These relationships are particularly important in the reporting of § No economically significant results are reported, and there is no known
Exploration Results relationship between reported widths and the geometry of any mineralisation
§ If the geometry of the mineralisation with respect to the drill hole angle § All intercepts are reported downhole as true width is not known
is known, its nature should be reported
§ If it is not known and only the down hole lengths are reported, there
should be a clear statement to this effect (eg 'down hole length, true width
not known')
Diagrams § Appropriate maps and sections (with scales) and tabulations of intercepts § Maps are provided in Figures 1-2. No significant discovery is reported
should be included for any significant discovery being reported These should
include, but not be limited to a plan view of drill hole collar locations and
appropriate sectional views
Balanced reporting § Where comprehensive reporting of all Exploration Results is not § The reporting is considered balanced
practicable, representative reporting of both low and high grades and/or
widths should be practiced to avoid misleading reporting of Exploration
Results
Other substantive exploration data § Other exploration data, if meaningful and material, should be reported § No other substantive exploration data other than that provided in the
including (but not limited to): geological observations; geophysical survey figures
results; geochemical survey results; bulk samples - size and method of
treatment; metallurgical test results; bulk density, groundwater, geotechnical
and rock characteristics; potential deleterious or contaminating substances
Further work § The nature and scale of planned further work (eg tests for lateral § Downhole EM of RAD002 is planned for 2023
extensions or depth extensions or large-scale step-out drilling)
§ Diagrams clearly highlighting the areas of possible extensions, including
the main geological interpretations and future drilling areas, provided this
